I've always picked up paper ephemera as an adjunct to cards. I am particularly drawn to snapshots. Some of my favorite pieces:
Satchel Paige snapshot from the team photographer, ca 1949:
1920s Biz Mackey snap from a Cal League season:
Velox snapshot of Jimmie Foxx with the Cubs:
Cubbies at spring training on Catalina snap, doing the Seven Dwarves routine:
Ernie Harwell, too cool for school, outside Ebbetts Field
QB Marshall Goldberg at a 1939 all star game:
I also appreciate AP News Library photos from the 1960s. They are about PC sized and have data and dates right on the front, which I appreciate:
And don't even get me started on team issues; like crack for me.
1958 Cleveland Browns TI Jim Brown rookie year:
This one took me years to find; 1971 rookie year Dr. J:
Images are from a pre-season exhibition against the Bullets, Wes Unseld defending. Not well; Dr. J lit him up for 30.
1959-60 Hawks TI, many HOFers:
1960-61 Celtics TI Bill Russell:
1968-69 Minnesota Pipers Connie Hawkins
MJ rookie year Bulls TI, small version:
1963 Cassius Clay mail response photo, w/mailing letter:
Love how they misspelled "resurrector"
